Economic issues

The generation of electricity by means of alternative energy sources is usually more expensive than traditional, coal-powered generators.[2][3] However, because renewable energy has no fuel costs and often requires less maintenance than fossil fuel generators, renewable energy is usually less expensive than fossil fuel-derived energy once initial capital costs are covered.[4] Renewable energy generators and power plants usually emits little-to-no pollution while operating, though they can cause other environmental effects, such as effects on neighboring ecosystems.[5]
